Book Description
Les cellules vivantes se caractérisent notamment par le fait qu'elles réalisent des échanges de matières d'énergie et d'information avec leur environnement. La bioénergétique cellulaire s'occupe particulièrement des échanges et des transferts d'énergie dans les cellules et ceux-ci sont très importants. Les cellules prélèvent dans leur milieu de l'énergie telle que l'énergie du rayonnement solaire ou l'énergie chimique potentielle de molécules organiques. Cette énergie est en partie transformée et permet de réaliser des synthèses, de créer et de maintenir des gradients, de faire fonctionner l'ensemble de la machinerie cellulaire. Au cours de ces processus l'énergie est finalement dissipée en travail et chaleur. Le but de cet ouvrage est de décrire de manière non exhaustive les principes et les modalités des échanges et des transferts d'énergie au niveau cellulaire. Il est destiné aux étudiants de premier cycle universitaire en Sciences de la Vie, aux étudiants des classes préparatoires BCPST et VETO ainsi qu'aux candidats aux concours externes et internes de recrutement de l'Education nationale (CAPES, Agrégation). L'ouvrage s'adresse aussi aux professeurs des classes de l'enseignement secondaire (qui pourront y trouver des compléments d'information) ainsi qu'à toutes les personnes intéressées par la biologie.

Book Description
The book covers major advances made in cellular bioenergetics, a central topic in biological and medical research. The chapters, contributed by authors representing major groups working in the field, extend from the latest advancements in X-ray crystallographic analysis of the atomic structure of energy transfer membrane proteins and analysis of their mechanism of action, to perspectives on the implication of their genetic and phenotypic defects in human diseases. The book, intended for researchers, clinicians and students, aims at providing an up-to-date appraisal of this rapidly developing biomedical field. The book consists of thirty-one chapters contributed by leading experts in the field of cellular bioenergetics. Three sections cover the X-ray crystallographic analysis, mutational analysis and mechanism of action of mitochondrial and prokaryotic respiratory enzymes, ATP synthase and mitochondrial carriers. One section deals with genetics and biogenesis of mitochondria. The fourth section covers genetic and phenotypic defects in mitochondrial energy transfer proteins associated with inborn and/or degenerative human diseases and aging.

Book Description
Bacteria can sequester metals and other ions intracellularly in various forms ranging from poorly ordered deposits to well- ordered mineral crystals. Magnetotactic bacteria provide one example of such intracellular deposits. They synthesize intracellular magnetic minerals of magnetite (Fe3O4) and/or greigite (Fe3S4) magnetosomes which are generally less than 150 nm and organized into one or multiple chain structures. The magnetosome chain(s) act like a compass needle to facilitate the navigation of magnetotactic bacteria by using the Earth’s magnetic field. Due to their ubiquitous distribution in aquatic and sedimentary environments, magnetotactic bacteria play important roles in global iron cycling. Other intracellular mineral phases have been evidenced in bacteria such as As2S3, CaCO3, CdS, Se(0) or various metal phosphates which may play as well a significant role in the geochemical cycle of these elements. However, in contrast to magnetotactic bacteria, the biological and environmental function of these particles remains a matter of debate. In recent years, such intracellularly biomineralizaing bacteria have become an attractive model system for investigating the molecular mechanisms of organelle-like structure formation in prokaryotic cells. The geological significance of intracellular biomineralization is important; spectacular examples are fossil magnetosomes that may significantly contribute to the bulk magnetization of sediments and act as potential archives of paleoenvironmental changes. In addition, intracellular mineral deposits formed by bacteria have potentially versatile applications in biotechnological and biomedical fields. After more than four decades of research, the knowledge on intracellularly biomineralizing bacteria has greatly improved. The aim of this Research Topic is to highlight recent advances in our understanding of intracellular biomineralization by bacteria. Magnetotactic bacteria are a system of choice for that topic but other intracellularly biomineralizing bacteria may bring a unique perspective on that process. Research papers, reviews, perspectives, and opinion papers on (i) the diversity and ecology of intracellularly biomineralizing bacteria, (ii) the molecular mechanisms of intracellular biomineralization, (iii) the chemo- and magneto-taxis behaviors of magnetotactic bacteria, (iv) the involvement of intracellularly biomineralizing bacteria in local or global biogeochemical cycling, (v) the paleoenvironmental reconstructions and paleomagnetic signals based on fossil magnetosomes, (vi) and the applications of intracellular minerals in biomaterial and biotechnology were welcomed.

The recently solved X-ray structure of the mitochondrial creatine kinase and its molecular biology cellular bioenergetics - the tradition we started in 1994 by publication of the focused issue of Molecular and Cellular are analyzed with respect to its molecular physiology and Biochemistry, volume 133/134 and a book 'Cellular Bio functional coupling to the adenine nucleotide translocase, as energetics: role of coupled creatine kinases' edited by V. Saks well as its participation, together with the adenylate kinase and R. Ventura-Clapier and published by Kluwer Publishers, system, in intracellular energy transfer. The results of the Dordrecht -Boston. In the present volume, use of quantitative studies of creatine kinase deficient transgenic mice are methods of studies of organized metabolic systems, such as summarized and analyzed by using mathematical models of mathematical modeling and Metabolic Control Analysis, for the compartmentalized energy transfer, thus combining two investigation of the problems of bioenergetics of the cell is powerful new methods of the research. All these results, described together with presentation of new experimental together with the physiological and NMR data on the cardiac results. The following central problems of the cellular bio metabolic and mitochondrial responses to work-load changes energetics are the focus of the discussions: the mechanisms concord to the concept of metabolic networks of energy of regulation of oxidative phosphorylation in the cells in vivo transfer and feedback regulation.
